More incentives for squad arena?

Ever since squad arena had its crystal rewards transferred to grand arena (love that since I now get more crystals this way) I find that participating in squad arena has been pretty much rendered useless since I've maxed out all available stock in the arena store years ago. With only credits and useless tokens for a shop with nothing more to offer than potential shard shop currency I just thought that it would be a little more interesting if the devs would offer us more incentive to play squad arena outside of completing daily activities
